• Multiplicity of highest weight (or singular) vectors associated with character chi_8 of Monster module.at n=44A034396
• Sin(n) decreases monotonically to -1.at n=35A046964
• a(0)=1; a(n) is the smallest integer > a(n-1) such that sin(a(n)) is closer to an integer (here 0 or -1) than sin(a(n-1)).at n=34A079037
• Numbers k such that the sum of the first k odd composites is palindromic in base 3.at n=7A118129
• Numbers n with property that for each single digit d of n, we can also see the decimal expansion of 2^d as a substring of n. Also n may not contain any zero digits.at n=16A135016
• a(1) = 1, and for each n >=2, a(n) is the smallest number such that 1/cos(a(n)) < 1/cos(k) for all k < n, so that 1/cos(a(1)) > 1/cos(a(2)) > ... > 1/cos(a(n)) > ...at n=34A172448
